Q75.0 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of craniosynostosis. The code is not specific and is NOT valid for the year 2026 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Craniosynostosis

Non-specific codes like Q75.0 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for craniosynostosis:

  • Q75.00 for Craniosynostosis, unspecified - NON-BILLABLE CODE

  • Use Q75.001 for Craniosynostosis, unspecified type, unilateral - BILLABLE CODE

  • Use Q75.002 for Craniosynostosis, unspecified type, bilateral - BILLABLE CODE

  • Use Q75.009 for Craniosynostosis, unspecified - BILLABLE CODE

  • Use Q75.01 for Sagittal craniosynostosis - BILLABLE CODE

  • Q75.02 for Coronal craniosynostosis - NON-BILLABLE CODE

  • Use Q75.021 for Coronal craniosynostosis, unilateral - BILLABLE CODE

  • Use Q75.022 for Coronal craniosynostosis, bilateral - BILLABLE CODE

  • Use Q75.029 for Coronal craniosynostosis, unspecified - BILLABLE CODE

  • Use Q75.03 for Metopic craniosynostosis - BILLABLE CODE

  • Q75.04 for Lambdoid craniosynostosis - NON-BILLABLE CODE

  • Use Q75.041 for Lambdoid craniosynostosis, unilateral - BILLABLE CODE

  • Use Q75.042 for Lambdoid craniosynostosis, bilateral - BILLABLE CODE

  • Use Q75.049 for Lambdoid craniosynostosis, unspecified - BILLABLE CODE

  • Q75.05 for Multi-suture craniosynostosis - NON-BILLABLE CODE

  • Use Q75.051 for Cloverleaf skull - BILLABLE CODE

  • Use Q75.052 for Pansynostosis - BILLABLE CODE

  • Use Q75.058 for Other multi-suture craniosynostosis - BILLABLE CODE

  • Use Q75.08 for Other single-suture craniosynostosis - BILLABLE CODE

Clinical Classification

Clinical Classifications group individual ICD-10-CM diagnosis codes into broader, clinically meaningful categories. These categories help simplify complex data by organizing related conditions under common clinical themes.

They are especially useful for data analysis, reporting, and clinical decision-making. Even when diagnosis codes differ, similar conditions can be grouped together based on their clinical relevance. Each category is assigned a unique CCSR code that represents a specific clinical concept, often tied to a body system or medical specialty.

Musculoskeletal congenital conditions

CCSR Code: MAL008

Inpatient Default: Y - Yes, default inpatient assignment for principal diagnosis or first-listed diagnosis.

Outpatient Default: Y - Yes, default outpatient assignment for principal diagnosis or first-listed diagnosis.

Convert Q75.0 to ICD-9-CM

Below are the ICD-9 codes that most closely match this ICD-10 code, based on the General Equivalence Mappings (GEMs). This ICD-10 to ICD-9 crosswalk tool is helpful for coders who need to reference legacy diagnosis codes for audits, historical claims, or approximate code comparisons.

Anomal skull/face bones

ICD-9-CM: 756.0

Approximate Flag - The approximate mapping means this ICD-10 code does not have an exact ICD-9 equivalent. The matched code is the closest available option, but it may not fully capture the original diagnosis or clinical intent.

Patient Education


Craniofacial Abnormalities

Craniofacial is a medical term that relates to the bones of the skull and face. Craniofacial abnormalities are birth defects of the face or head. Some, like cleft lip and palate, are among the most common of all birth defects. Others are very rare. Most of them affect how a person's face or head looks. These conditions may also affect other parts of the body.

Treatment depends on the type of problem. Plastic and reconstructive surgery may help the person's appearance.
